Here's a little script that scrapes all PHP function names from this page, and outputs a prefix-compressed Perl Compatible Regular Expression matching them. Useful for syntax highlighting.
<?php
$html = file_get_contents('http://php.net/manual/en/indexes.functions.php');
preg_match_all('/<li><a href="function.[^>]*>([a-zA-Z0-9_]*)<\/a>/', $html, $matches);
$funcs = $matches[1];
print '\b(?:';
$prefixes = [''];
foreach($funcs as $i => $func) {
while(substr($func, 0, strlen($prefixes[0])) !== $prefixes[0]) {
print ")";
array_shift($prefixes);
}
if ($i) print '|';
while(true) {
$common = $func;
for($j = $i+1; $j < count($funcs); $j++) {
$lookAhead = $funcs[$j];
$maxLen = min(strlen($lookAhead), strlen($func));
for($ch = 0; $ch < $maxLen; $ch++) {
if ($lookAhead[$ch] !== $func[$ch]) break;
}
$newCommon = substr($common, 0, $ch);
if (strlen($newCommon) < strlen($prefixes[0])+2) break;
$common = $newCommon;
